Will resolve according to data from Pew Research Center, when a report is next published using data from 2024 or 2025.
The latest summary, with historical numbers 1995-2023, is here:
The last four data points are:
2019: 27.0%
2020: 26.50%
2021: 30.00%
2022: 30.40%
If Pew Research Center does not publish a report of this statistic with data from 2024 or 2025 by the end of 2025, then a comparable alternative will be found (with advice from the community). If a comparable alternative cannot be found (for instance, if alternatives do not agree with the historical data from Pew), then this question will resolve N/A.
Update 2025-12-16 (PST) (AI summary of creator comment): The creator plans to resolve to N/A after close, stating that Pew data is unavailable and no comparable Fortune 500 alternative was found.
Sadly, it looks like we won't get the data. For what it's worth, it looks like the answer is "probably yes", based on this data for Russell 100 and Russell 1000: https://5050wob.com/wp-content/uploads/pdf/2025-annual-gender-diversity-index-report.pdf

However, since that's not the same as Fortune 500, and since I'm the only YES holder on this market anyway, I'm planning on N/A resolution after close.
First quarter of 2024: "Analysis of the Russell 3000 shows women hold only 29.7% of board seats, with a minimal 0.3% increase from the previous quarter and 0.8% from the previous year. Only 30.7% of the 587 new board positions are filled by women, the lowest percentage since 2017."
